How do I install a single defrost heater element with a dual element heater?
You would install the heater the same way as the original heater by screwing to the bracket. What changes is where the wire on the left side goes. The kit comes with a yellow wire that if the original blue wire is too short you can cut the connector off and splice the yellow wire to it to make it longer. This will allow the wire to go across where the other wire comes down the right side of the evaporator and connect to the element. You can connect either wire to the terminals and there is a jumper on the other end of the heater connecting them together.
